Where the parcel data comes from
This is a statewide map, not a county site. Delaware FirstMap State Parcels covers parcels across Delaware, and Sussex County is one part of it. A statewide layer can trail the county's own books by weeks or months, so treat it as a fast first look rather than the final word. When we tested the link in October 2026 it opened with no login and no fee.
Searching for a parcel, step by step
- Open the statewide map with the button above.
- Search for an address in Sussex County, or zoom to the county on the map.
- Click a parcel to see the attributes the state layer includes.
- Write down the parcel number and use it for records searches with the Sussex County assessor or recorder.
Rural addresses don't always geocode well. When that happens, zoom in by hand and click the parcel, or search by owner name.

Maps vs. surveys
The lines you see online are approximate. They're good for finding a lot and its parcel number, but a legal boundary question needs the recorded plat or a surveyor.
